Well, I agree with your general sentiment to a point, but I would say that in the lexicon of the day, "AI" and "LLM" are not synonymous. LLM's are one (current very popular and useful) approach to AI, but only a VERY casual observer would conflate the two terms as being completely equivalent. To me, it goes without saying that the world of AI is bigger than just LLM's.

But since we're talking about an article in Fortune, maybe it's fair to think of this strictly from a lay-person perspective.

Also, to the extent that it matters, I'm not necessarily saying "build something (completely) different than an LLM". I can picture a world with systems that include LLM's that interoperate with other components that do more of the "world model" and "commonsense reasoning" parts, yielding an aggregate system that does more/better than any of the parts could do in isolation.
